    JBL continually engages in research related to product improvement. Some materials, production methods and designrefinements are introduced into existing products without notice as a routine expression of that philosophy. For thisreason, any current JBL product may differ in some respect from its published description, but will always equal orexceed the original design specifications unless otherwise stated.

    DrivePack systems can be remotely controlled and monitored usingHiQnet System Architect software. A Windows-based application, itprovides an intuitive, unified platform for system configuration andoperation of not only JBL DrivePack-equipped systems, but any otherHiQnet-compliant audio devices in the signal chain, like the VP (VenuePerformance) Series. HiQnet System Architect enables the unified layoutof on-screen product control surfaces, and simple preset configuration ofan entire system made up of HiQnet-compliant products across multiplebrands and product classes.

    Advanced remote control and diagnostic capabilities, custom controlpanel creation, unified event logging and error reporting for the entiresystem, and the recall of presets on all connected HiQnet devices areincluded. In addition, the application enables a user to copy / paste likeparameter values from, and to, multiple products across the HiQnetnetwork.

  • DPIP (Standard dbx Input Module)JBL DrivePacks are equipped with a modular input bay and are available in severalversions. The standard DPIP input module features analog audio inputs andsophisticated onboard digital signal processing technology. Precision bandpasslimiting, pre-equalization filters and automatic self-test functions ensure optimizedperformance. Front panel controls include a 32-position detented rotary attenuatorcalibrated in 0.5 dB steps which provides a 16 dB range of control. This can beuseful for setting up downfill shading or overall system gain structuring. Anotherfeature is the Enable Subwoofer Filter button. This is a momentary-contact typeswitch which enables or disables the selected function. On subwoofer applications,the low-pass frequency is set to 80 Hz. For full-range systems used with subwoofers,the high-pass is raised to 80 Hz.

    DPAN (Optional HiQnet Network Input Module with Analog Audio)In addition to all of the features included on the standard input module, the DPANadds 100 Mb Ethernet networking functionality and HiQnet compatability. It enablesremote control and monitoring via HiQnet System Architect software. NetworkControl and Monitoring is enabled by the DrivePack Software Device Panel
